Two toes, often confused. There are two: the Greville Chester toe, a one-piece cartonnage (linen, glue and plaster) toe in the British Museum, and the Cairo toe, a three-part articulated wooden toe sewn with leather thread, found on a mummy at Sheikh Abd el-Qurna near Luxor and now in Cairo. They are frequently mixed up in popular accounts. The Cairo toe is the more sophisticated device and is usually dated to roughly 950-710 BC; the Greville Chester toe is generally placed somewhat later. Both show clear wear.

The evidence that it was used in life. This is the crucial point and it is genuinely evidential, not assumed. The wear patterns are consistent with walking; the Cairo toe shows signs of having been refitted, meaning someone adjusted it after the original fitting; and it was attached to a foot whose amputation had healed well before death. A purely funerary prosthesis — to make the body whole for the afterlife, which Egyptians certainly did care about — would not need refitting and would not wear. Both purposes may well have applied at once.

It was tested, in a gait laboratory. Researchers at the University of Manchester made replicas of both toes and had volunteers with the same amputation walk on them, with and without Egyptian-style sandals. The replicas performed measurably better than no prosthesis at all, particularly for push-off, and the articulated Cairo design outperformed the rigid one. That is an unusually strong verification for an object of this age — most reconstructions are never tested against a living body.

Why the big toe specifically. The hallux carries a large share of the load at push-off, and losing it disturbs the whole gait cycle. It also matters more in a sandal culture than in a shoe culture: the sandal thong runs against the big toe, and without one the sandal will not stay on the foot correctly. The design solves a mechanical problem and a footwear problem at the same time — and the fact that it is jointed, rather than a simple carved lump, says the maker understood that a toe has to bend.
